Evaluation of Brain Tissue or Cerebrospinal Fluid with Broadly Reactive Polymerase Chain Reaction for <i>Ehrlichia, Anaplasma</i> , Spotted Fever Group <i>Rickettsia, Bartonella</i> , and <i>Borrelia</i> Species in Canine Neurological Diseases (109 Cases)

The results of this investigation suggest that microorganisms in the genera Ehrlichia, Anaplasma, Rickettsia, and Borrelia are unlikely to be directly associated with canine MEM in the geographic regions evaluated. The role of Bartonella in the pathogenesis of GME warrants further investigation.
